specification of Letters Patent.

Application led January 17, 1914. Serial No. 812,742.

To aZZ rwhom it may concern:

Be it known that I, MICHAEL SWEENEY, a citizen of the United States of America, residing at Niagara Falls, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Screens, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a new type of screen and the principal object of the invention is to so construct the improved screen that it may be readily adjusted to t a window.

Another object of the invention is to provide the screen with an improved type of mesh covering which is crimped thus permitting the wire mesh to accommodate itself to the size of the frame.

Another object of the invention is to provide an improved type of frame which is so constructed that the metal strips will form clamps for holding the wire mesh in place, and also forming means for keeping themselves in an interlocked position.

With these and other objects'in view this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

This invention is illustrated in the accompanying drawings, wherein;

Figure 1 is a perspective view of the frame with a portion of the wire mesh removed. Fig. 2 is an elevation of the screen.

Fig. 3 is a sectional view along the line 3 3 of Fig. 2. Fig. 4 is a sectional view taken along the line 4-4 in Fig. 2. Fig. 5 is a perspective view of the metal strip at one side of the screen. Fig. 6 is a fragmentary sectional view showing the manner in which the side strips grip the end strips. Fig. 7 is a perspective view of a portion of the wire mesh.

In the accompanying drawings; the numerals 10 and 11 represent the end strips of the screen which end strips are preferably formed of wood or some other rigid material. These end portions are provided with dovetailed tongues 12 at their ends which are provided so that the end strips 10 and 11 can be tions of the side strips 13 and 14. These side strips have their end portions engaging the end strips, as shown in Fig. 6 and are secured in place by the screws 15 which pass through the dovetailed tongues 12. The side strips 13 and 14 are dovetailed in cross section throughout their entire length and the inner end portion of the strips 13 telescope into the strips 14 so that the two sections of the screen frame will have no 'tendency to come apart. The wire mesh has its end portions secured to the end strips 10 and 11 by the securing beads 16, and is corrugated or crimped, as shown in Fig. 3, so that the two end sections of the screen may be drawn apart or moved toward each other without the screen mesh being torn or crumpled. It will also be noted that this crimped screen mesh 17 will permit the two sections to be used without each section being provided with its own screen. This does away with the danger of the wire of the two sections gapping apart, thus leaving a space through which insects can pass. It should also be noted that the side strips 13 and 14 grip the side portions of the wire mesh, and thus hold the same tightly in place and prevent any danger of the wire mesh slipping out of place when moved to a contracted position. l/Vhen this screen is is use the window is open and the screen is then placed in the window frame and the end portions of the frame drawn apart by means of the knobs 18 until the screen is the proper size to fit the opening. The wire mesh permits the frame sections to be adjusted to any eXtent desired and will at all times fit tightly in the frame of the screen without leaving any space through which insects can pass.

That is claimed, is

A. screen comprising a frame having end portions, side strips secured to said end portions and being formed of sheet metal, said side strips constituting a substantially U-shaped channel portion, having their side edges inwardly pitched to constitute a substantially dovetailed channel, said side strips fitting one over the other to constitute a sliding eXpansible frame, a wire mesh sheet gripped by the end porfiXedly secured to said end portions and becording to the adjustment of said end poring arranged in a corrugated manner betions relative to each other. 10 tween said end portions, and said wire mesh In testimony' whereof Iy hereunto aX my sheet Yhaving its edges fitting in said dovesignatnre in presence.otwowitnesses tailed channels, whereby said wire mesh MICHAEL SWEENEY. sheetnwill be held against accidental dis-V placement from said channel .portions and may be allowed t expand and Contract ac l/Vitnesseszw Gnonon .Nass'oiy, PATRICK H.
